OEM Carrier Furnace Control Transformer 40VA 120V–24V for Model PG8JAA060155ACJA (Part# HT01BC116 / HT680054)

This OEM Carrier step-down transformer is the factory-specified replacement for the Carrier PG8JAA060155ACJA gas furnace. The control transformer converts 120V line voltage down to 24V AC to power the entire low-voltage control circuit — including the thermostat, gas valve, inducer, and control board relay coils. When this transformer fails, the furnace loses all 24V signal power: the thermostat goes blank or unresponsive, the system won't call for heat, and no components respond. If you're reading 0V between your R and C terminals on the control board, this transformer is the first component to test and replace.

  • Specs: 40VA rating | 120V primary (input) | 24V secondary (output) | 60 Hz | Single phase | Foot-mount bracket | Wire lead connections with insulated female quick-connect terminals
  • OEM vs Generic: OEM transformers are wound to exact factory VA tolerances, ensuring the 24V signal stays stable under full load. Generic units can sag under load, causing intermittent lockouts and nuisance trips on the control board's fuse — a problem OEM eliminates entirely.
  • Install difficulty: 2/5 — Shut off power at the breaker before touching any wiring. Tools needed: flathead and Phillips screwdrivers, multimeter, needle-nose pliers. Photograph all wiring connections before disconnecting. Verify 0V across secondary terminals before confirming transformer failure.
  • Warranty: 1-year OEM manufacturer warranty. In-stock units ship same business day from our warehouse when ordered before cutoff.

Compatibility: Designed for the Carrier PG8JAA060155ACJA packaged gas furnace. OEM part number HT01BC116 has been superseded by updated OEM part HT680054 — both are fulfilled as direct drop-in replacements. Also cross-references: HT01BC115, HT01BB126, HT01BC120, HT01AW115, and several other legacy Carrier/Bryant transformer part numbers. Confirm 120V primary and 40VA rating on your unit's data plate before ordering. Need fitment verification? Our team checks compatibility before you buy.

My thermostat has no power. What failed?
Thermostat with no display = failed 24V transformer (or blown control board fuse). Check the 3A/5A fuse on the control board first ($1–$5 fix). If fuse is good but no 24V output from transformer, replace transformer.
Is this transformer compatible with Bryant or Payne too?

The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.
Should I use OEM or aftermarket for my Carrier transformer?
OEM recommended for reliability and warranty compatibility. OEM parts match exact factory specifications for proper fit, performance, and safety. While aftermarket alternatives cost less upfront, the risk of improper fit and reduced lifespan usually makes OEM the better value long-term.
